WATER-CLOSET BEND.

Specification of Letters Patent.

Patented Dec. 3, 1907.

Application filed February 28.1907- Serial No. 358,909.

To all whom it may concern:

-Be it known that I, CHARLES A. DREIER, a citizen of the United States of America, and a resident of Chicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in Water-Closet Bends, of which the following is a specification.

This invention relates to plumbing, and its main objects are to provide an improved, durable, and inexpensive form of water and gas-tight joint for pipes which are especially suited for the connection between water closet bends and the bowls thereof; and to provide a joint of this class which may be readily adjusted through a considerable range to suit the different conditions which arise 1n diflerent buildings. These objects are accomplished b the device shown in the accompanying rawings, in which:

Figure-1 1s a section of a water closet bend constructed according to this invention. Fig. 2 is a top plan of the same.

The body part 1 of the bend is of a usual form' having a hub 2 ofusual form at the end of its upper branch. This hub has an inner annular shoulder 3 at its lower end and has I an enlarged interior adapted to receive the end of an adjoinin pipe and permit of being filled with lead am calked in the usual manner. The bend 1 is connected by means of an ad'ustable section of pipe or thimble, with the closet bowl, which is not shown in the drawings. This thimble is formed of two telescoping parts having threaded engagement with each other and permitting of adj usting the length of the thimble. end of the lower part or ring 4 is beaded similarly to the ?s igot end of a cast iron' pipe and is ads. to to be seated upon the shoulder 3 within the hub 2.

The upper part 5 of the thimble is internally threaded at its ends. The art 4 is so proportioned that the lower end 0 the up er part 5 of the thimble will extend inward of the hub 2 in all positions of ad'ustment of said parts, thus insuring that w en a fillin of lead or other suitable material is calke into the space between the thimble and the hub, .a' erfectly as-tight and water-ti ht joint willbeforme bothbetween the thim 1e and the hub and between the two arts of the thimble. The thimble has a orizontally-disposed flange 6 at its upper end for connectin it to the closet bowl. This flange is prefera 1y provided with an external y threaded nipple .which extends into the The lower thimble 5, the j ointbetween the thimble and flange being rendered water and gas-tight by means of. an interposed gasket 10. The purpose of the threaded oint between the thimble and flange is to permit the flange to be removed for the purpose of calking the joint between-the hub 2 and the thimble. The flange 6 is grooved at 7 near the inner periphery of its upper face to provide a seat for a gasklet between said flange and the closet In connecting up a closet by means of the bend which is herein described, the flange 6 is screwed into position on the thimble and the parts of the thimble are then adjusted with respect to each other, so that the flange is in proper relation with the lower end of the closet bowl when the lower part 4 of the thimble rests upon the shoulder 3. The flange 6 is then removed and the usual filling of oakum 8 and lead- 9 is then laced into the space between the hub 2 and the thimble, being finally calked so as to make a permanent joint. The flange 6 is then screwed back lnto position on the upper end of the thimble and is ready for connection with the closet bowl completed.'

What I claim as my invention and-desire to secure by Letters Patent is:

1. A pipe having a hub at one end, an annular shoulder located inward of said hub, a second pipe extendinginto said hub, and a ring having threaded engagement with said second pipe and adapted to bear on said shoulder for adjusting said second pipe with respect to the first, said hub being suitably formed to permit sealing material to be filled into the space between said hub and second pipe for sealing the joint, substantially as described.

2. A pipe having a hub at one end, a thimble extendi into said hub and havi an adjustable jolnt for varyin the length 0 the thimble, said joint being ocated inward of the hub, said hub being suitably formed to' provide a space around the thimble adapted to be filled with material for renderi airtight both the joint between said thimble and hub. and the joint in said thimble.

3. A ipe having a hub at one end, a shoulder at t e inner end of said hub, a thimble extendi into said hub and resting u on said sho der, said thimble being forms of two parts telescoping each other and adjustable with respect to each other for varying the length of the thimble, and said hub being 1 oiisly sealing suitably formed to permit of filling the spae between said hub and thimble'for simultanethimble and hub and the joint between the parts of said thimble.

4. A pipe having a hub at one end, a shoulder at the inner end of said hub, a thimble extending, into said hub and supported by said shoulder, said thirnble comprising two tubular parts having ascrew-threaded joint located inward of the hub, and said hub being suitably formed to permit material to be filled between said thimble and the hub for both the joint between said.

ble extending into said hub and havin an adjustable jolnt for varyingthe length 0 the thimble, said joint being located-inward of the hub, said hub being suitably formed to provide a space aroundthe thimble adapted to be filled with material for rendering airtightboth the joint between said thimble and hub and thejoint in said thi1nble,' and a flange at the outer end of said thimble having screw-threaded engagement therewith.

Signed at Chicago this 19th day of February, 1907.
